In the mid-1700s, France found its influence waning among midwestern tribes as it contested for Native American trade and military alliances with Great Britain. Shortly after Miami chief Memeskia (also known as Old Britain or La Demoiselle) moved his village to Pickawillany, British traders were given permission to establish a small post in the village, which was deep in the territory claimed by France. When French demands to evacuate the post failed, Charles Langlade led a party of 250 Ottawa and Ojibwe warriors and French Canadians in a surprise attack on the Miami village on June 21, 1752. The trading post was destroyed, British traders were taken to Detroit as prisoners, and Memeskia was executed. Pickawillany was completely abandoned soon after. As a prelude to the French and Indian War, the Battle of Pickawillany fueled land claim and trading right conflicts between France and Britain.
